Table 63. Comparator 2 Characteristics - STMicroelectronics STM32L151RE Manual

Electrical characteristics
1. Guaranteed by characterization results.
2. The delay is characterized for 100 mV input step with 10 mV overdrive on the inverting input, the non-
inverting input set to the reference.
3. Comparator consumption only. Internal reference voltage not included.
